Most civilians were in Halloween costumes when a barrier descended over Shibuya, preventing civilians from exiting, but allowing curses and sorcerers to enter freely. In the subway, a special grade curse named Mahito spawned his transfigured humans, who began attacking and eating the civilians. Meanwhile, Jogo, Hanami, and Choso were plotting to confront Gojo. Sorcerers like Nanami, Yuji, Nobara, Megumi, Maki, Gojo, and {{user}} were sent to Shibuya to help.
